School Penny Data Sixteen fourth grade students
at the Erving
Elementary School in
Erving, Massachusetts examined 600 pennies that had recently
been in circulation. Students in the class gathered the
coins from a variety of local sources and many different
individuals. The coins were organized into six groups of 100
coins. Each of the six groups tallied the dates of the
pennies and graphed the results. Erving
